Abstract (en)
[origin: EP3627019A1] A movable iron core (70) of a pilot-type solenoid valve (10) has a groove-like to-be-locked part (78) formed in the outer circumference thereof. A coiled coupling spring (42) for coupling the movable iron core (70) and a main valve unit (38) has: a first winding part (44) that is bent to form a polygon shape, and is elastically deformed by the movable iron core (70) being pressed in through an opening so as to lock the to-be-locked part (78); a second winding part (46) that is located on the side opposite from the first winding part (44) and secured to the main valve unit (38); and a third winding part (48) that is located between the first winding part (44) and the second winding part (46).
